We look at the division of 89941991 by 556 
The aim is to understand the frequency of 556 in 89941991.

Step 1:
When dividing 8 by 556, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 556

Going ahead to step 2:
The number 556 fits into 89 0 times, leaving a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Append the next digit (9) from the dividend to 89 and continue with: 899 / 556

Step 3:
899 divided by 556 is 1 with a remainder of 343.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 343 after subtracting 556 from 899.
Bring next digit (4) of the dividend behind the 343 and repeat the process: 3434 / 556

Let's proceed to step 4:
556 can be fit into 3434 6 times, resulting in a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 3336 from 3434, we get 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 556

Advancing to step 5:
The number 556 fits into 981 1 times, leaving a remainder of 425.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Subtracting 556 from 981 leaves us with 425.
Include the next digit (9) from the dividend after 425, then repeat: 4259 / 556

Going ahead to step 6:
4259 divided by 556 is 7 with a remainder of 367.
Put 7 as the next digit of the answer. 
Result so far: 1617.0
Subtracting 3892 from 4259 leaves us with 367.
Take the next digit (9) from the dividend and append it to 367, then repeat: 3679 / 556

Moving on to step 7:
556 goes into 3679 6 times with a remainder of 343.
Record the quotient 6 as the next digit in the result. 
Result so far: 16176.0
The remainder is 343 after subtracting 3336 from 3679.
Take the next digit (1) from the dividend and append it to 343, then repeat: 3431 / 556

Going ahead to step 8:
When dividing 3431 by 556, we get 6 with a remainder of 95.
Record the quotient 6 as the next digit in the result. 
Result so far: 161766.0
If we take 3336 away from 3431, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 9:
950 divided by 556 is 1 with a remainder of 394.
The next digit of our result is 1. 
Result so far: 161766.1
If we take 556 away from 950, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 10:
When dividing 3940 by 556, we get 7 with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 161766.17
The remainder is 48 after subtracting 3892 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
If we divide 480 by 556, we get 0 and a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 161766.17
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 12:
556 goes into 4800 8 times with a remainder of 352.
Use 8 as the next digit of our solution. 
Result so far: 161766.1708
Deduct 4448 from 4800 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 13:
556 can be fit into 3520 6 times, resulting in a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 161766.17086
If we subtract 3336 from 3520, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 14:
556 can be fit into 1840 3 times, resulting in a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 161766.170863
Deduct 1668 from 1840 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 15:
If we divide 1720 by 556, we get 3 and a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 161766.1708633
The remainder is 52 after subtracting 1668 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 161766.1708633, and the remainder is 5.2e-07.
